It's notable that our ancestors spent their time building observatories because they were scared shitless of another one of those recurrent cataclysms happening (due to some deadly star approaching?) and now we see how our modern societies are falling again into the same neurosis. Debunkers may say what they want but I think humanity's fate has been defined by heavenly phenomena, we carry it in our collective subconscious (as Velikovsky correctly remarked).
